All you Need to Know About Sanitary Butterfly Valves

Sanitary butterfly valves are some of the most widely used in different industries. They are used to regulate the flow of liquid or gas in pipes. Butterfly valves are preferred because of their simple design and ability to control the flow of substances with minimal resistance. Sanitary butterfly valves have become popular in the food and pharmaceutical industries because they meet stringent quality control and sanitation requirements. This blog post will discuss everything you need to know about sanitary butterfly valves.

What are Sanitary Butterfly Valves?

Sanitary butterfly valves are a type of manual valve designed for use in pipes carrying liquids, water, and other sanitary materials. Unlike conventional ball or gate valves, these special valves have a flat disc-shaped hydraulic element inside the centre of their body. When this disc is turned 90 degrees clockwise or counterclockwise, it either opens or closes to regulate fluid flow as needed. They provide a high degree of flow control with minimal effort and can be used in clean air systems where sterile processes such as food industries are concerned due to their excellent sealing capabilities, ensuring no particles escape. Sanitary butterfly valves are also lightweight and easy to install, making them cost-effective while offering dependable operation over extended periods.

Everything You Need to Know About Sanitary Butterfly Valves

Sanitary Butterfly Valves Construction

A sanitary butterfly valve usually consists of two discs attached to a central shaft, which rotates to control the flow of substances through the valve. The disc design ensures that no liquid or gas is trapped in the valve, avoiding contamination. The valve has a smooth surface to prevent bacteria buildup, making it easy to clean. Sanitary butterfly valves are typically made from stainless steel, which is resistant to corrosion, and in some cases, they may be coated with Teflon.

Sanitary Butterfly Valves Operation

It would help if you turned the central shaft to operate a sanitary butterfly valve. The disc is still in the flow path when the valve opens, which means a minimal pressure drop across the valve. As an operator, you can easily tell the valve’s position by looking at it, as the disc is visible when fully opened or closed. Sanitary butterfly valves have become increasingly popular in the food and pharmaceutical industry due to their easy operation, reliability, and low maintenance requirements.

Advantages of Sanitary Butterfly Valves

Sanitary butterfly valves are the choice for industries that demand high sanitary standards. They offer many benefits, including easy operation, reliability, and minimal pressure drop. They are also quick and easy to install and maintain, which makes them cost-effective. The ease of cleaning is another advantage of sanitary butterfly valves, as they have no debris pockets or joints that could trap bacteria. Notably, the simplicity of the valve structure translates to less downtime for maintenance, which means production is not affected unnecessarily.

Sanitary Butterfly Valve Applications

The food and pharmaceutical industries are the primary users of sanitary butterfly valves. In the food industry, they are used to regulate the flow of different liquids such as dairy products, juices, and beer. In the pharmaceutical industry, they are used to regulate the flow of different drugs and chemicals. Sanitary butterfly valves are also used in chemical processing, where they are used to control the flow of corrosive substances such as acids and alkalis.

How to Select the Right Sanitary Butterfly Valves?

There are several factors to consider when selecting a sanitary butterfly valve. The first factor is the right material, which should match the substance you intend to regulate. You should also consider the valve’s size and pressure rating, which should match your piping system. Additionally, you should consider the degree of automation required because several sanitary butterfly valves can be automated, leading to more precision and control.

Conclusion:

In conclusion, sanitary butterfly valves offer an excellent solution for applications that require high sanitation standards. They are preferred by food production, pharmaceutical production, and chemical processing industries. With an appropriate material selection, sizing, and automation, sanitary butterfly valves provide reliable and precise flow control with minimal pressure drop. Given the benefits of sanitary butterfly valves, they offer an excellent choice for various production applications.
